The monograph is the product of twelve former officers in the Japanese Army. All served in Manchuria during the brief. war that lasted from 9 August to 15 August 1945, all were taken captive by the Soviets, and all were subsequently repatriated to Japan. Each of the contributing authors has dealt with his subject separately, following a prescribed outline, and providing as much detail as was available to him through notes or memory.
